[quote name='mgariti']1.) First, you must determine which GENESIS you have, V. 1, 2, or 3. If you have the 3rd model, stop here! Neither SegaCD or 32X are compatible.
2.) INSTALLING SEGA CD: On the very right side of the GENESIS, there is a plastic cut-out piece about 3-inches long. Pull that out directly to the right... NOT UP OR DOWN! Inside is a keycard, take the bright orange plastic guard off. A green computer card will be exposed...DON'T TOUCH! Make sure it is not cracked. Place the genesis on the left platform next to the CD-drive. Gently slide the card into the hole beside the CD-drive.
IF YOU HAVE A GENESIS 2, SKIP TO 3.
2b.) A Genesis 1 has a headphone jack in front. Run a male-male headphone dubbing cord to the SegaCD audio mixer, then a stereo audio line to the TV, doing away with the Genesis's mono cord.
3.) INSTALLING 32X: Run a new model GENESIS's stereo A/V cord from the A/V out in the back of the 32X. *(Old model Genesis 1, use only Video, [for which you need ANOTHER adapter from Sega if one's not provided] follow step 2b for sound). Use prong-to-prong (short) cord between the 32X "in" port and Genesis's "out" port.[/QUOTE]
and finally, you must register your 32x with your state dept. of energy who will provide you with the "secret cord" that you must install directly to the genesis' motherboard. After installing the secret cord, it must be certified Kosher by your local rabbi. Only then will the 32x function properly.
